0.7L Collapsible Water Bottle

Took it on a long trail walk and clipped it to my belt loop when it was empty—that's when the foldable design really shines. The wide mouth makes filling and cleaning a breeze, and freezing it overnight kept my water cold for hours.

It's been in my freezer overnight twice now and the wide mouth makes it easy to fill with ice cubes. It takes up almost no room in my daypack once it's empty, which is exactly what I needed.

I keep one clipped to my backpack on every hike, and it's the first bottle I've owned that actually disappears when empty—the fold-flat design saves serious space. Ice cubes go in without a struggle through the wide mouth, and the whole thing freezes solid without cracking. My dog gets his own fill
